--In this microlearning, we’ll explore how to view and customize topic alerts within your eMagiz environment. Customizing these alerts allows you to tailor the trigger conditions and thresholds to better fit your specific needs, enhancing how you monitor and respond to topic activity. We’ll cover the two types of topic triggers available and guide you through configuring them to suit your requirements. This will help you ensure your alerts are as effective and relevant as possible. Should you want to learn more about the standard alerting that eMagiz offers, please check out this [[microlearning>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.crashcourse-platform-manage-alerting-gen3||target="blank"]].
++In this microlearning, we will focus on how you can customize your queue alerts by configuring the trigger conditions and thresholds, which raise an alert and notify people when those points are passed.

  == 1. Prerequisites ==
  * Basic knowledge of the eMagiz platform
--* Basic knowledge of alerting in the eMagiz platform
  == 2. Key concepts ==
--This microlearning focuses on customizing the topic alerts that are existing in each of the environment of your model (i.e., Testing-Acceptance-Production). By customizing we mean further configuring the trigger conditions and thresholds of your topics, so they better suit your needs and requirements.
++This microlearning focuses on customizing the queue alerts for each environment in your model. By customizing: we mean further configuring the trigger conditions and thresholds of your queues from the general default settings provided by eMagiz, so they better suit your needs and requirements.
--* eMagiz applies the same set of triggers to all topic.
--* There are two topic trigger options that eMagiz currently provides:
--** Minimum throughput check
--** Messages behind check
--* Recipients are defined on the topic level.
++* eMagiz applies the same set of triggers to all JMS queues
++* There are four queue trigger options that eMagiz currently provides:
++** Consumers check
++** Queue load check
++** Inactivity check
++** Periodic activity check
++* Recipients are defined on the queue level.
--== 3. Topic Alerting ==
++== 3. Queue Alerting ==
--As all our alerting now works is that we have divided them up in various segments that are accessible via Manage.
++To enhance the observability of your integration landscape while running in the current generation runtime architecture, we have added a new feature to our Manage phase called "Dynamic Alerts." You can access this functionality via the "Alerting" menu in Manage. Then, with the help of the "Trigger" overview, you can view all triggers in your environment. On the top of the list, you will see all [["static" alerts>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.crashcourse-platform-manage-alerting-gen3||target="blank"]] as defined by eMagiz below that you will see all "dynamic" alerts that you and your fellow team members (with sufficient rights) can view, edit and delete.
--[[image:Main.Images.Microlearning.WebHome@crashcourse-platform-manage-alerting-in-emagiz-topic-alerts-overview.png]]
++We offer alerting on seven types.
--Here, when you navigate to Manage->Alerting->Triggers, you will find all the topics that are generated by eMagiz currently existing within your model, along with the trigger conditions and thresholds that are applied to each of these topics. In the following sections, we will discuss how you can tune these topics triggers to your needs.
++* Error message
++* Log message
++* Queue consumers
++* Messages in queue
++* Queue throughput
++* Messages added to topic
++* Topic consumer messages behind
--{{info}}Contrary to the queue alerting we do not offer any default configuration as eMagiz given the widespread implementation of event streaming in the community which prevents us from defining relevant default triggers that would apply in almost all cases. As a result, the default configuration on topic level is that the alert is **disabled** and **no** thresholds are defined{{/info}}
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-trigger-options.png]]
--=== 3.1 Customize Default Values ===
++First, we will discuss the configuration of each trigger type. Subsequently, we will discuss defining which recipients will be notified and how to alter the default congestion control settings (as this is the same for each trigger type).
--Changes to the default values will only apply to topic triggers that are set to use the default values, and not to those you have already customized. To modify the default values configured by eMagiz, you can click the "Configure defaults" button at the top of the topic trigger list.
++=== 3.1 Error message ===
--{{info}}Note that if your account does not have edit rights in Manage for a specific environment, you will see a "View defaults" button instead.{{/info}}
++On top of the "static" alert that is autogenerated by eMagiz on Error messages, you can add additional "dynamic" alerts that only trigger when an error message is raised for which a specific header contains a particular value. This is most likely relevant when a specific error message with certain characteristics (i.e., a particular header value) needs to be sent to a different set of recipients.
--[[image:Main.Images.Microlearning.WebHome@novice-alerting-customize-topic-alerting--customize-default-triggers.png]]
++To define the trigger, fill in the header's name and the expected value. On top of that, you can fill in a description that will be added to the alert received via email. Once this is filled in, the configuration could look as follows.
--Here, you will get a pop-up page where you can configure the default values of your topic triggers. The details of each of the triggers will be discussed in the next section. But, what is important to note here is that, here, you have the "Reset to eMagiz defaults" button to reset the default values to the values provided by eMagiz as defaults (i.e. disabling them). Next to that, at the bottom of the pop-up, you will find the "Update defaults" button, which will apply the default values that you have configured to all topic triggers that are set to use the default values. By clicking this button, the new default values will be put into effect immediately.
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-error-message-configuration.png]]
--Additionally, on this page, you can also find the "Notifications" tab that allows you to configure which recipients that you want to receive the notifications from the alerting. If you want to learn more about this notifications and how to configure it, please refer to this [[microlearning>>Main.eMagiz Academy.Microlearnings.Intermediate Level.Alerting.intermediate-alerting-setting-up-notifications-gen3||target="blank"]].
++=== 3.2 Log message ===
--=== 3.2 Customize Topic Alerting ===
++On top of the "static" alert that is autogenerated by eMagiz on Log messages, you can add additional "dynamic" alerts that only trigger when a log message contains a specific phrase. This is likely when you log something on which you want to alert when it happens.
--Next to customizing the default values for all topic triggers, you can also modify the trigger configurations for individual topics. To customize these topic triggers to better suit your needs, you can click the edit buttons (green paper and pencil buttons) located at the end of each topic trigger. By doing so, you will get a pop-up page that allows you to further customize the conditions and thresholds of your topic triggers, which will be discussed in the following.
++To define the trigger, fill in the phrase you want to check. On top of that, you can fill in a description that will be added to the alert received via email. Once this is filled in, the configuration could look as follows.
--==== 3.2.1 Minimum throughput check ====
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-log-message-configuration.png]]
--[[image:Main.Images.Microlearning.WebHome@novice-alerting-customize-topic-alerting--minimum-throughput-check.png]]
++=== 3.3 Queue consumers ===
--{{info}}This alert checks whether a topic receives at least the specified number of messages within a 10-minute window. If the count remains below the threshold for the entire window, a Problem alert is triggered. Please provide the threshold that suites the integration. You can customize this threshold as needed. Additionally, you can specify the instructions to be included in email notifications sent to recipients and in the alert message displayed in the Manage->Alerting->Alerts.{{/info}}
++On top of the "static" alert that is autogenerated by eMagiz on Queue consumers, you can add additional "dynamic" alerts that only trigger when the number of consumers on a (specific) set of queues is below a certain threshold.
--==== 3.2.2 Messages behind check ====
++To define the trigger, determine the threshold you want to check (i.e., 2). Subsequently, specify whether on which queues (or all queues) you want eMagiz to check for this condition. No further action is needed if you want to check on all queues.
--[[image:Main.Images.Microlearning.WebHome@novice-alerting-customize-topic-alerting--messages-behind-check.png]]
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-queue-consumers-all-queues.png]]
--{{info}}This alert monitors consumer lag and triggers a Problem alert if any consumer group exceeds the defined threshold for 10 consecutive minutes. Please provide the threshold that suites the integration. For more information check out the helptext on the component{{/info}}
++You can uncheck the checkbox if you want to check on a specific (set of) queue(s). As a result, the "Add" and "Remove" buttons are displayed by eMagiz, through which you can add and remove queues to the trigger.
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-queue-consumers-specific-queues.png]]
--{{info}}Upon saving, these custom values will apply immediately, putting the new check into effect. Additionally, you will notice that the "Settings" status of the topic trigger you just customized has changed from "Default" to "Custom". Similarly, on this page, you can also find the "Notifications" tab that allows you to configure which recipients that you want to receive the notifications from the alerting of a specific topic. If you want to learn more about this notifications and how to configure it, please refer to this [[microlearning>>Main.eMagiz Academy.Microlearnings.Intermediate Level.Alerting.intermediate-alerting-setting-up-notifications-gen3||target="blank"]].{{/info}}
++When you press the "Add" button, a new pop-up will appear through which you can select the queues for which you want the trigger to be activated. In this pop-up, you can choose one (or more) queues and press the "Select" button to add them to the trigger.
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-queue-consumers-queue-selection.png]]
++
++{{info}}Note that when you want to select multiple queues at once, you cannot press "Enter" to Save your selection. In this case, you need to press the "Select" button to save your choice.{{/info}}
++
++Once you have selected the queue(s) and pressed "Select," eMagiz will close the pop-up and add the queues to the trigger.
++
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-queue-consumers-queue-selection-result.png]]
++
++=== 3.4 Messages in queue ===
++
++On top of the "static" alert that is autogenerated by eMagiz on Messages in a queue, you can add additional "dynamic" alerts that only trigger when a queue holds more than X messages. Logically, the X can be determined by the user. Subsequently, define whether on which queues (or all queues) you want eMagiz to check for this condition. No further action is needed if you want to check on all queues.
++
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-messages-in-queue-all-queues.png]]
++
++You can uncheck the checkbox if you want to check on a specific (set of) queue(s). As a result, the "Add" and "Remove" buttons are displayed by eMagiz, through which you can add and remove queues to the trigger.
++
++{{info}}This process of adding and removing specific queues works identically, as explained in the section on Queue consumers.[[Queue consumers.>>||anchor="H3.3Queueconsumers"]]{{/info}}
++
++Once you have selected the queue(s) and pressed "Select," eMagiz will close the pop-up and add the queues to the trigger.
++
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-messages-in-queue-queue-selection-result.png]]
++
++=== 3.5 Queue througput ===
++
++For this category you can add additional "dynamic" alerts that only trigger when the throughput on one or more queues is more or less than X messages per Y minutes. Subsequently, define whether on which queues (or all queues) you want eMagiz to check for this condition. No further action is needed if you want to check on all queues.
++
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-queue-throughput-all-queues.png]]
++
++You can uncheck the checkbox if you want to check on a specific (set of) queue(s). As a result, the "Add" and "Remove" buttons are displayed by eMagiz, through which you can add and remove queues to the trigger.
++
++{{info}}This process of adding and removing specific queues works identically, as explained in the section on Queue consumers.[[Queue consumers.>>||anchor="H3.3Queueconsumers"]]{{/info}}
++
++For this trigger, additional criteria can be configured that allow you to define when eMagiz needs to validate this configuration (i.e., Occurence). With the help of this configuration option, you can specify when the trigger needs to be evaluated. An example could be only on Monday between 04:00 AM and 05:00 AM.
++
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-queue-throughput-occurence-config.png]]
++
++=== 3.6 Messages added to topic ===
++
++For this category, you can add additional "dynamic" alerts. These alerts only trigger when the messages added to one or more topic is less than X messages per Y minutes. On top of the number of messages (X) and the timeframe (Y), you can define whether to validate this on a specific topic or all topics. Note that the default configuration is that the alert applies to all topics.
++
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-messages-added-to-topic-all-topics.png]]
++
++You can uncheck the checkbox to check on a specific (set of) topic(s). As a result, the "Add" and "Remove" buttons are displayed by eMagiz, through which you can add and remove topics to the trigger.
++
++{{info}}This process of adding and removing specific topics works identically, as explained in the section on Queue consumers.[[Queue consumers.>>||anchor="H3.3Queueconsumers"]]{{/info}}

++
++=== 3.7 Topic consumer lag ===
++
++For this category, you can add additional "dynamic" alerts. These alerts only trigger when one (or more) consumer groups lag by X messages on one (or more) topic(s). Note that the default configuration is that you, as a user, need to specify for which topic(s) the alert applies, as consumers' behavior can vary widely.
++
++{{info}}This process of adding and removing specific topics works identically, as explained in the section on Queue consumers.[[Queue consumers.>>||anchor="H3.3Queueconsumers"]]{{/info}}
++
++Once filled in, the solution should look similar as follows.
++
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-topic-consumer-lag-selected-topics.png]]
++
++=== 3.8 Recipient(s) configuration ===
++
++You can select your recipients when you switch from the "Trigger" to the "Output" tab. In this overview, you can choose both eMagiz users and external recipients.
++
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-recipient-config.png]]
++
++{{info}}Note that when you define multiple external recipients, you need to separate each email address with a comma to make it work.{{/info}}
++
++=== 3.9 Congestion control configuration ===
++
++In the same "Output" tab, you can also define the congestion control configuration. The default configuration is that congestion control will be activated once more than ten alerts are triggered in the last ten minutes. So should you want to reduce this number, you can do so here.
++
++[[image:Main.Images.Microlearning.WebHome@novice-alerting-dynamic-alerting--dynamic-alert-congestion-control-config.png]]
++
++{{warning}}Note that we advise only reducing the number under the congestion control if the ten default is too high. We do **not** advise deactivating the congestion control as this can cause an explosion in the number of received notifications.{{/warning}}
